PUMP-BUCKET.

SPECIFICATION forming part of Letters Patent No. 276,695, dated May 1, 1883. 1 4 Application tiled October 25, 1B2. (No model.)

and Figs. 3 and 4, top views ofthe rod-straps,`

the position of the rod being indicated by the broken lines. In Fig. 3 but one of the straps bears upon the rod. In Fig. 4 both ofthe straps are in place. y

The same letters of reference denote the saine parts.

The present. invention relates more especia-lly to the mode ot' connecting therod-straps with the other parts ofthe construction.

A represents the packing ot' the buckets. It is secured to the rings, B C. The rings are provided with the ianges b c, respectively, the flanges fla-ring, and the packing at its lower edge being held between the tianges. The rod D is attached to the` straps E E. The straps, at their lower ends, pass through and are secured to the rings B O, each strap having a tlange, c, which bears upon the upper side of the upper ring, B, and the end e' ofthe strap below the ring O being threaded to receive a nur, F. The tightening ofthe nut draws the rings B C together, serving both to fasten the rod straps to the rings and also to clamp the packing between the ring-flanges. In pump-buckets ot' the kind under consideration the rod-straps in use are apt to work loose in the rings. 'lo obviate this difficulty and to enable the Iod-straps to be'properly secured to the rings ofthe bucket,

' the nuts F are made in the form of lock-nutsthat is, the nuts have shoulders or projections f, andthe ring C, on its under side, is provided with projections c'. The projections of The operation of connecting thevarious parts of the bucket is as follows: The packing being between the ring-anges, the straps Varepassed through the rings BV C., and the nuts are screwed onto the ends of the straps; or, rather, as the nuts, by reason of the ring projections c', cannot be rotated, the straps are screwed into the nuts, and after the nuts have been thus tightened against the ring U the rod D is attached to the straps by means of the bolts Gr, substantially as shown in Fig.

1. It is necessary for the straps, when tightened upon the rings, to be turned so as to bring the upper ends ot' the straps properly against the rod, as shown in Fig. 4; but generally,when the straps are iirst tightened upon the rings, it will be found that the straps, at their upper ends, are not turned toward the rod, but are at an angle therewith, as indicated by the position of the strap E', Fig. 3. The procedure then is to loosen thestrap in the nut and to turn the nut around upon the strap suitably to correspond to the angle at which the strap diverges from the rod, whereupon tbe strap is again tightened to the rings B C and the bolts G passed through and properly secured to the straps and rod. It is an advantagel to have the nuts furnished with several projections, c', as thereby the straps can be more readily and effectually adjusted and tightened to the rings and rod.

I claim- `l. In apump-bucket, the combination ofthe packing A, the rings B and C, respectively having as an integral part the lianges b and c, the rod D, and stra-ps E E', screw-threaded on their lower-ends, e', and locked by nuts F, substantially as described.

2. In a pump-bucket, the rings C c', of a single piece, and having projections c', the rodstraps E E', screw-threaded on their ends c', and shouldered nuts Ff, substantially as de-V scribed.4
